This thing would still be huge but 90MB for a fractal sheesh. Probably makes a rather large gif file too I'm imagine. Thank God I don't still use Winderz. Linux Mint 11 had no problem with it but MS would have baulked. It is a nice image though, wonder what it was calculated on. -----Original Message----- From: Tony Hanmer Sent: Feb 1, 2012 7:57 AM To: Fractint and General Fractals Discussion Subject: [Fractint] Polynomial Roots I don't understand this completely, but it sure makes a nice image! (The image it links to, http://jdc.math.uwo.ca/roots/polynomial_roots.png , is 90 MB as a png file but over 1 GB as a .tif file, be warned... it's 16263 x 23000 pixels in size!) Is there any way that this calculation, and zooms of it, could be rendered in Fractint?

And the main reason is the way that JPEG does not usually preserve the original pixels when saved, which is why it is defined as a "lossy" file system.
